Are you experiencing frustrating electrical issues in your Cadillac CTS? Problems like flickering lights, malfunctioning power windows, a radio with a mind of its own, or random warning lights are common signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of perplexing symptoms. This VIN-programmed Body Control Module is the definitive solution to restore your vehicle’s functionality and peace of mind.
We make the repair process simple. Unlike the dealership, which requires you to have the vehicle towed in for programming, we program this module to your vehicle’s specific VIN before we ship it. This means it arrives at your door ready for installation. Simply provide your VIN after purchase, and we’ll handle the rest, loading it with the latest GM software updates for optimal performance.

Installation and Post-Install Information
After you install the module, your vehicle should return to normal operation. However, in some cases, additional steps known as ‘relearn’ procedures may be necessary. These are simple procedures for a technician with a capable scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor recalibration may be required on certain models.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Is this BCM ready to install when I receive it?
Yes! We program the module to the VIN you provide after your purchase. This ensures it’s ready for installation upon arrival, saving you a trip to the dealership.
How do I give you my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we receive this information.
What is a BCM and what does it control?
The Body Control Module (BCM) is a computer that manages many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and radio.
What if the airbag light comes on after I install the new BCM?
This is a rare but possible scenario. It means the new BCM needs to be electronically synced with the airbag system’s computer (SDM). A qualified technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back?
No. This product has no core charge, so you can keep your original module without any extra fees or hassle.
